Lose Weight with Small Calorie Reduction
A reduction of just 200 calories a day combined with aerobic exercise four times a week produced greater weight loss and better heart health in obese, sedentary adults than exercise alone or a 600-calorie reduction plus exercise, reports a new study in Circulation. Researchers from the Wake Forest School of Medicine, in Winston-Salem, North Carolina, tested 160 adults ages 65 to 79. Those that combined exercise with 200 fewer calories a day lost 10 percent of their weight, about 20 pounds, over five months. They had a 21 percent average increase in the aorta’s ability to expand and contract, a key indicator of heart health. Measures of aortic stiffness did not change significantly for the exercise-only group or the 600-calorie-reduction-plus-exercise group. Weight loss was similar for both calorie-reduction groups, even though one group consumed nearly three times fewer calories per day.
